Northern helmeted curassow  (Pauxi pauxi)

This large and unusual-looking bird is named for the bizarre bluish-grey fig-shaped casque on its forehead (2) (4). The plumage is predominantly black, with a greenish and bluish gloss to the mantle and breast, while the belly, under-tail coverts and tail tip are a contrasting snowy white, and the bill and legs are a conspicuous coral red (2). Although the sexes are usually alike, there is a rare morph of the female that has rufous-brown and black barred plumage (2) (4). Males are larger than females, but both are robust and strong (5).
